[EN] In accordance with the Building Regulations Law and the upcoming passing of the Building Technical Code, our society demands more quality in buildings. Some aspects related to people’s wellbeing,
such as thermal insulation and hygrothermal comfort of the spaces must also be considered. This presentation is about thermal bridges, that is, the parts of the building envelope where the otherwise uniform thermal resistance is significantly changed, and as a consequence, there is a minor thermal resistance compared to the rest of the closures. The scope of this communication is a clear comprehension of the problems caused by thermal bridges: extra heat transfer, condensations, mould growth. It is possible to design and build every kind of construction without thermal bridges, however it is difficult to solve their negatives effects once they have taken place.
